LOCOMOTIVE-BOILER.

SPECIFICATION formingpart of Letters Patent No. 637,186, dated November14, 1899. Application filed January 27, 1899. Serial No. 703,572. (Nomodel.)

To all whom it may concern.-

Be it known that I, CORNELIUS VANDER- BILT, J r., of the city of NewYork, borough of Manhattan, in the county and State of New York, haveinvented a new and Improved Locomotive-Boiler, of which the following isa full, clear, and exact description.

The object of the invention is to provide a new and improvedlocomotive-boiler arranged to materially increase the strength of theboiler, to resist all strain due to expansion and contraction of theparts or other causes, and to avoid rupture of the sheets, thearrangement also giving a more effective heating-surface, notably in thefire-box, to insure a rapid generation of steam.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification,-in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a longitudinal central sectional elevation of theimprovement. Fig. 2 is an enlarged end elevation of the same. Fig. 3 isan enlarged transverse section of the same on the line 3 3 in Fig. 1.Fig. 4 is alike view of the same on the line 4 4 in Fig. 1, and Fig. 5is a similar View of the same on the line 5 5 in Fig. 1.

The shell of the locomotive-boiler is provided with a barrel or outersection A, disposed horizontally and made cylindrical and having asmoke-box A projecting from the outer end of the barrel. The rear endofthe barrel is connected with the small end of the 'wagon top A in theform of a cone, the rear or base end being connected with a fire-boxsection A inclined rearwardly and downwardly from said wagon-top A as isplainly indicated in Fig. 1.

The section A is made cylindrical in crosssection, as isplainlyindicated in Figs. 2 and 3, and in said section is arrangedeccentrically a fire-box B, likewise made cylindrical in cross-section,the rim or wall of said fire-box being corrugated in a transversedirection, as is plainly indicated in Fig. 1. The forward end of thefire-box B is suspended by links 0 from the forward top portion of thefire-box section A the lower or bottom portion of the fire-box restingon suitable supports G,carried by the section A asillustrated in Fig. 3.The open end of the fire-box Bis riveted or otherwise secured to thefront sheet A of the firebox section A (See Fig. 1.)

The fines E extend from the-firebox fluesheet B to the flue-sheet F,formed with a rim having transverse corrugations F, as is plainly shownin Fig. 1, the corrugations extending a suitable distance from the innersurface of the barrel A to permit a proper yielding in a longitudinaldirection of the fluesheet upon expansion and contraction of the fines Eto relieve the barrel A of undue strain, it being understood that theextreme outer end of the corrugated sheet is riveted in the usualniannerto the barrel or outer section A.

By the arrangement described the flnes E stand at an angle to the axisof the barrel A and the wagon top A and the fine-sheet F stands at anangle to the outer end of the barrel-that is, is inclined to thevertical-as is plainly indicated in Fig. 1, and by tilting the fire-boxB the water-space below the fire-line at the back is reduced to increasethe depth above the fire-line, thus giving a more effectiveheating-surface in the back end portion of the fire-box. By notsubmerging the for ward end to the same extentthat the rear end issubmerged a still more effective heating surface is obtained, therebyinsuring a rapid generation of steam. It is further evident that by thearrangement described, especially by the cylindrical form of fire-boxand barrel, the strength of the boiler is materially increased and arupture of the sheets is not liable to take place, as unequal strainsare avoided, and the connection and form of the several sections aresuch as to resist all strain due to expansion and contraction of thevarious parts and to the pressure of the generated steam.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-'- 1. Alocom otive-looiler, provided with afirebox made cylindrical in cross-section and hav ing its rim or wallcorrugated in a transverse direction, and a fire-box section in whichthe fire-box is placed eccentrically, the axis of the fire-box sectionbeinginclined to the horiand the forward end of said firebox beingsubmerged to a less extent than the rear end, to increase the effectiveheating-surface for a rapid generation of steam, substantially as shownand described.

2. A locomotive-boiler comprising a shell having a horizontallydisposedbarrel-section, a conical wagon-top, a fire-box section inclineddownwardly and rcarwardly from the base of thesaid conical wagon-topsection a fire-box hung eccentrically in said fire-box section and withits axis inclined to the horizontal, an inclined flue-sheet in thebarrelsection, and fines extending from the front end of the fire-box tothe said line-sheet and approximately at right angles thereto, snbstantia-lly as shown and described.

. 8. A locom0tive-boiler comprising a horizontally-disposed barrel-section, a conical Wagon-top section, a cylindrical fire-box sec tioninclined downwardly and rearwardly from the base of said wagon-topsection, a fire-box made cylindrical in cross-section and having itswall or rim corrugated in a trans verse direction and hung eccentricallyin the said fire-box section, a fine-sheet in the said the fire-box tothe said fine-sheet, snbstam tially as shown and described.

In a steam-boiler, the shell comprising a horizontally disposedcylindrical barrel, a conical wagon-top in axial alinement with thebarrel and a cylindrical fire-box section in combination with acylindrical firebox eccentrically disposed in the said fire-box sectionand seen red thereto at its open entrance end, and fines extending fromthe forward closed end of the said fire-box in an upward and forwarddirection to connect with the flue-sheet in the said barrel,substantially as shown and described. a

In a steam-boiler, a cylindrical fire-box section, and a cylindricalfire-box eccentrically mounted in the said fire-box section and inclinedthereto in a longitudinal direction, substantially as shown anddescribed.
